Get live USD prices

Current on-chain USD spot for every asset, read from Chainlink feeds on chain 4663.

GET /api/prices returns the current USD spot for every asset, read on-chain from each token’s Chainlink price feed. Assets with no live feed report source: "none" and omit priceUsd rather than showing a faked number.

GET /api/prices · public, no token required · 60 requests per 60 seconds per IP. Base URL, response envelope, and error shapes: conventions.

Feeds use 8 decimals and are already corporate-action adjusted (splits, dividends), so the feed value is the token’s full USD price. Every read folds into one eth_call through Multicall3 on chain 4663.

Parameters

None. The route prices the whole universe on every call.

Response

{ prices, asOf }. asOf is the ISO timestamp of the response. prices maps each asset symbol to an AssetPrice:

Field	Type	Description
`symbol`	string	The asset ticker.
`priceUsd`	number	USD per whole token. Omitted when the asset has no live feed or the price is stale.
`source`	string	`"chainlink"` when a fresh feed answered, `"none"` when there is no usable live price.

Example

curl "https://monvera.best/api/prices"

{
  "prices": {
    "AAPL": { "symbol": "AAPL", "priceUsd": 231.02, "source": "chainlink" },
    "NVDA": { "symbol": "NVDA", "priceUsd": 171.84, "source": "chainlink" },
    "SPY": { "symbol": "SPY", "priceUsd": 614.03, "source": "chainlink" },
    "SPCX": { "symbol": "SPCX", "source": "none" }
  },
  "asOf": "2026-07-08T14:03:11.204Z"
}

The SPCX entry is the shape for an asset with no live feed: source: "none" and no priceUsd key.
